Subject: [PATCH] Docker with macOS support

Created a new snowblock that contains the `~/.docker/config.json`
configuration file. The file for the `iceowl` host has been configured
to ensure the macOS Keychain is used to store tokens instead of saving
them as plain text into the config file.

Related to epic GH-131
Closes GH-136

+# Docker
+
+> Docker is the leader in the containerization market, an open-source project that automates the deployment of software applications inside containers by providing an additional layer of abstraction and automation of operating-system-level virtualization on Linux.
+
+## Setup
+
+### macOS Keychain
+
+To ensure that registry login tokens are stored in the macOS Keychain instead as plain text in the `~/.docker/config.json` file the configuration file must be adjusted:
+
+```json
+{
+  "credsStore": "osxkeychain"
+}
+```
